Niseko Area Mountain Bike Association

Mountain Biking in Niseko

Building mountain bike trails and community in Niseko, Hokkaido.

What snowsports did for Niseko’s winters, mountain biking will do for its summers.

NAMBA is the nonprofit behind Japan’s largest mountain bike network. Twin Peaks opened in 2023; today there’s 30+ km of trail across four parks, and Niseko is on its way to being the place to ride in Asia.
